MAINTENANCE
'Inspect Handset' warning
8:4 This light will flash when it is advised
that the handset may need descaling.
Remove the handset and clean following
the instructions below. To reset the
'INSPECT HANDSET' warning, follow the
instructions given in 5.56.
Cleaning the Handset
Also refer to instructions supplied with
handset.
8:5 To obtain the best performance from
your shower, the handset must be cleaned
regularly, maybe as often as once a week
in hard water areas.
8:6 This is because the fine outlet holes
can become blocked with scale and this
will affect the pattern of the spray and
cause the heater to perform poorly.
8:7 The easiest and most effective
method of cleaning your handset,
regardless of which type you have with
your shower, is to soak it in a proprietary
descalant. For best results the handset
should be left to soak overnight.
8:8 The handset with rubber spray outlets
can be cleaned by simply rubbing one's
hand over them firmly to dislodge the
scale.
INSPECTION
8:9 We recommend that in the interests
of safety the shower and its electrical
installation is checked by a qualified
electrician at least every two years.

flow and result in extremely hot water
being emitted from the spray head.
A damaged hose could completely block
the outlet of the shower; the resulting
increase in pressure could burst a
weakened or damaged hose.
2.13 Do not install the shower in a situation
where the water in it could freeze. Any
damage caused by freezing will not be
covered by the guarantee.
WARNING. If you suspect your shower
is frozen, DO NOT SWITCH ON. If you
have switched on, SWITCH OFF
IMMEDIATELY. Refer to Fault Finding
(p17).
2.14 Do not leave the infirm, disabled
users, or young children unattended in the
shower.
2.15 Before stepping into the shower,
always test the temperature of the spray
with your hand.
2.16 Switch off at the isolating switch after
use. This is a safety procedure
recommended with ALL electrical
appliances.
2.17 As with all electrical appliances, it is
advisable to have your shower and
installation checked at least every two
years by a competent electrician, to
ensure that there is no deterioration due
to age and usage.
2.18 Shampoo and shower gel should be
stored using the gel hook and soap dish
(where provided) and must not be placed
on top of the shower unit.
HOW AN INSTANT ELECTRIC
SHOWER WORKS
2.19 When the user starts the shower by
pressing the start/stop button, the flow
control lets in the water. If there is
sufficient water pressure, the pressure
switch will turn on the heating elements.
2.20 The element in the tank will start to
heat the water and this takes typically 10-
20 seconds.
2.21 By controlling the flow rate of water
over the heating elements, it will be
warmed up to the correct temperature.
Reducing the flow rate will increase the
water temperature and vice versa.
2.22 The shower has high, medium and
low settings that give further control of
temperature.
2.23 The temperature of the incoming
water varies, mains water can be as low
as 5°C in the winter and as high as 20°C
in the summer. This affects the output
temperature of the shower which is only
able to raise the temperature of the water
by a given amount, depending upon the
flow rate.
